Even the not-so-keen-eyed observer has probably noticed by now that the PlayStation Move's logo doesn't really look like a letter "M." That's because it's a letter "A," as in "Arc," the name which, according to multiple Sony sources who wished to remain anonymous, is what the peripheral was to be called at retail until the company was refused a trademark on the Arc name. In fact, we've been told that the change to "Move" was made quite recently, which further explains the incongruous logo.
If you think "Move" is an odd name for Sony's motion controller, these same sources assured us that we got lucky – many of the other proposed names following the trademark denial were ranged from silly to awful, they said. When we suggested that "PlayStation Boogie" was about as bad as we could imagine, we were told, "Actually, that's an improvement over a lot of them."
Keep an eye on the Move logo -- we wouldn't be surprised if Sony's marketing department adds a little extra blue ink before E3, making it a true (stylized) letter "M."
